Arsenal have not confirmed when they expect the centre-back to return, but he is likely to miss this weekend's FA Cup game against Hull and is now a doubt for Tuesday's game against Barcelona at the Emirates Stadium.

Gabriel had been picked ahead of Per Mertesacker by Arsene Wenger recently, although the Arsenal manager said ahead of the Leicester game that Gabriel still struggles with English after a year in London, making his communication on the pitch an issue.

Fellow centre-back Laurent Koscielny had to be substituted at half-time against Leicester with a dead leg, but is expected to fit for the Barcelona game.

Gabriel played for Vitoria between 2010 and 2013 before joining Spanish club Villarreal. He was brought in by Wenger in the 2015 January transfer window but has mainly been a backup to Koscielny and Mertesacker thus far.
